We combine semi–analytical methods with a ultra-high resolution simulation of a cluster (of mass 2.3 × 10hM⊙, and 4 × 10 6 particles within its virial radius) formed in a standard CDM universe to study the spatial distribution and orbital properties of the present–day descendents of Lyman Break galaxies (LBG). At redshift 3 we find a total of 12 halos containing at least one Lyman Break galaxy ...

We report the discovery of six compact, starburst galaxies with redshifts 2.3 < z < 2.8 and r-band magnitudes 19.8−20.5 in the Quasar Catalog of the Sloan Digital Sky Survey First Data Release (SDSS DR1). The SDSS spectra of these objects resemble the composite spectrum of Lyman Break Galaxies (LBGs) at z ≈ 3, but the galaxies are 4−5 magnitudes brighter than an “L∗” LBG and 2 − 3 magnitudes br...

BACKGROUND Autologous bone harvested from the iliac crest is the gold standard for lumbar spinal fusion. However postoperative donor site pain and morbidity have been reported. Local bone graft is insufficient and contains some soft-tissue attachment. Therefore, Healos (DePuy Spine, Raynham, MA, USA) is currently bone graft substitute that was introduced for spinal fusion with good results but ...

For constructing the best local codebook for image compression, there are many Vector Quantization (VQ) procedures, but simplest VQ procedure is Linde–Buzo–Gray (LBG) procedure. Techniques such as Gaussian Dissemination Function (GDF) used searching process in generating a global particle swarm optimization (PSO), Honeybee mating (HBMO), and Firefly (FA) procedures. However, when velocity very ...

A p-adic modification of the split-LBG classification method is presented in which first clusterings and then cluster centers are computed which locally minimise an energy function. The outcome for a fixed dataset is independent of the prime number p with finitely many exceptions. In the end, the methods are applied to the construction of p-adic classifiers in the context of learning.

BACKGROUND Black ginseng has a more potent biological activity than non-steamed ginseng. We investigated the effects of long-term intake of dietary black ginseng extract (BG) on antioxidant activity in aged mice. We also compared the effects of BG on cognitive deficits with those of white ginseng extract (WG) and red ginseng extract (RG). METHODS Ten-month-old mice were fed an AIN-93G-based d...

We present out results on the cross-correlation of Lyman break galaxies (LBGs) around three damped Lyα absorbers (DLAs) at zabs ≃ 3 from deep (μI,AB(sky) ≃ 27.6mag arcsec) UBV I KPNO 4m/MOSAIC images. The large area of the MOSAIC images, 0.31 deg or ∼ 65 × 65h 71 Mpc co-moving at redshift z = 3, allows us to probe the clustering of LBGs on scales up to 20 Mpc co-moving. Our survey covers a tota...

Abstract We present bright [C ii ] 158 μ m line detections from a strongly magnified and multiply imaged ( ∼ 20–160) sub– L * M UV = − <mm...

We report the discovery of six compact, starburst galaxy candidates with redshifts 2.3 < z < 2.8 and r-band magnitudes 19.8−20.5 in the Quasar Catalog of the Sloan Digital Sky Survey First Data Release (SDSS DR1). The SDSS spectra of these objects resemble the composite spectrum of Lyman Break Galaxies (LBGs) at z ≈ 3 (albeit with some differences and broader spectral lines), but the systems ar...
